We optimize swimming shapes of three-dimensional self-propelled
swimmers by
combining the CMA- Evolution Strategy with a remeshed vortex
method. We analyze the
robustness of optimal shapes and discuss the near wake vortex
dynamics for optimal
speed and efficiency at Re=550. We also report preliminary
results of optimal shapes
and arrangements for multiple coordinated swimmers.
